Hello guys!

I have a math problem, i need scale circles with sop solver, but i need scales linearly, but for each iteraction (frame) scaling acts exponentially.

i tried use some formulation on transform inside sop solver with “log()” but with no sucess…

what i need is circles scaling equidistantly, so i need some trick to scale linearly.
and yes, need reside inside a sop solver.

any ideas?

attached a image showing above the problem, and below (manually made) what i need output…

thanks in advance.
